Sunday marked 10 years since the U.S. Supreme Court issued its ruling in KSR International Co. v.Teleflex Inc., rejecting the test that was used by the U.S. Patent and Trademark Office, patent attorneys and district courts for determining if a patent is too obvious. This weeklong Law360 Expert Analysis series explores the decision’s effect on obviousness analysis and the patent landscape.

Below are four key statistical takeaways regarding the significance of KSR on patent litigation in the past 10 years and how that impact may be waning as KSR approaches its teenage years.
